IM PROVEMENT IN ENDLESS RAILWAV'S'.

Specification forming part of Letters Patent No. 132,152, dated October15, 1872.

To all whom it may concern Beit known that I, JESSE FRYE, of the city ofBrooklyn, in the county of Kings and State of New York, have invented acertain novel and useful Endless Railway; and I hereby declare thefollowing to be a full, clear, and exact description thereof, referencebeing had to the accompanying drawing, which is lettered to correspondwith and form a part of -the specification.

To enable the public to understand the nature of my said invention, andthose skilled in the mechanic arts to construct and operate the same, Iwill describe it as follows, to wit:

Figure 1 is a perspective drawing of my endless railway T, showing aside elevation and an oblique top view. Fig. 2 is a vertical section ofthe same, inclosed in a cylindrical tunnel longitudinally divided intocompartments P P P. Fig. 3 is a plan of a section of my endlessrolling-gear to operate upon my endless tracks T T, and to receive andoperate the endless platforms E E, Fig. l.

Fig. 4 represents a plan ofthe endless track or tram-way. P P P P arethe dividing partitions of the same, all arranged inside of a tunnel orarchway. (See Fig. 2.) N N mark the locality and arrangement ofdrivingwheels provided with projecting fin gers or teeth, which areoperated by any suitable engine located below the track, and connectingwith the cog gearing-wheels G G', which are operated in oppositedirections at any suitable locality along the line of the endless track,say every five miles (more or less) apart.

This application is confinedto the endless counterbalancing railway ortrack, and not to the rolling-gear or endless platform, as I propose tomake three separate applications for Letters Patent to more fullyprotect the several parts of my invention.

The tracks or tram-ways T T T T being endless, I do away with the use ofturn-tables, switches, turn-outs, and frogs, such as used upon ordinaryrailroads. These endless tramways or tracks are made of either metal orwood or wooden stringers T, overlaid with metal, and the tracks arefirmly secured together by metallic cross-ties V, made of angleiron, sothat the tracks orY stringers T T rest upon the horizontal flanges ofthe cross-ties V, and are secured or bolted to the same from the underside thereof. (See Fig. 2.) I construct my endless railway inside of asingle tunnel or archway, either above or below the earths surface,excepting at the ends thereof, where the tracks will be laid upon aneasy curve of not less than 1920 ft. radius for the narrow gage, and2640 ft. radius for the wide gage; this should be the minimum andmaximum of all the curves along the entire line of the road. The railsupon the narrow gagewillbe laid sixteen inches (more or less) apart fortwentyve (more or less) inch cars, and the rails on the wide gage willbe about twenty-five inches apart for the reception of thirty-nine (moreor less) inch cars, capable of seating two persons abreast. However, Ido not confine myself to the above width of track or capacity of cars,but adopt that 'width of tracks and cars that will suit the diameter ofthe tunnel or archway through which the road may pass. I conwith smoothmetallic ceiling to separate the moving cars, and to prevent theresistance of the air upon the moving trains, to allow the same to movewith the least resistance, as well as to prevent the concussion of theopposing currents of air which would be produced by.

the rapid passage of trains so near together in opposite directions.

The central passage H, Fig. 2, (through the tunnel,) must be welllighted, and all the compartments must be thoroughly ventilated by theintroductionof fresh air supplied by airengines located at eachpower-station or other localities along the line, so as to dischargecondensed air into the passing trains in the same direction with themoving cars, which, in a small degree, assists the motor power. This airpasses'down between the sides of the metallic ceiling and the edges ofthe endless platforms or carrier E into the central passage, and fromthence it passes freely through large pipes or conduits to the surface.

The above-described railroad tracks must be of the best quality ofmaterial, rmly laid upon substantial ties, and the end joints thereofmust be united by a long mitered lap, securely bolted or otherwisesecured so as to form one united endless rail or track, capable ofresisting any lateral or vertical strain from any cause whatever.

Thenovelty of my invention consists in the construction of one uniformendless railroad track, of either wood or metal, without turn-- Anendless railway track or tracks, T T T T, of either woodor metal,secured by means of angle-iron V or other ties, and united at the endsof the different sections of the rail by means of elongated miteredjoints so as to forln a uniform endless track, united by circular ends OO', and separatedby partitions P P P Pf, all arranged inside of anarchway or tunnel, in the manner and for the purposes substantially asabove set forth.

In testimony whereof I hereunto subscribe my name in the presence of twowitnesses.

JESSE FRYE.
